B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
V = pi r^2 h
isolate h by moving pi & r^2 to the other side.
Move with opposite operation from multiplying which is dividing, so
h = V / (pi r^2)

Joelle spent 1 1/2 hours studying for her science test. Rileigh studied 3/4 for of Joelle‛s time. What fraction of an hour did Rileigh spend studying?
Answer: 1¹/₈ hours
Step-by-step explanation:
Joelle spent 1¹/₂ hours reading and Rileigh spent 3/4 of that time.
To find out how much time Rileigh spent, multiply the fractions but first convert the improper fraction to a proper fraction:
= 1¹/₂ = 3/2
= 3/2 * 3/4
= 9/8
= 1¹/₈ hours
Answer:
1 1/8
Step-by-step explanation:
it's just right
What is an equation in point-slope form of the line that passes through the point (1,−5) and (−5,−6)
HELPPPP
Answer:
y + 5 = ¹/₆(x - 1)Step-by-step explanation:
The slope of a line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(1, -5) ⇒ x₁ = 1 , y₁ = -5
(-5, -6) ⇒ x₂ = -5 , y₂ = -6
[tex]m=\dfrac{-6+5}{-5-1}=\dfrac{-1}{-6}=\dfrac16[/tex]
Point-slope form of equation of a line with givem slope m and passing through point (x₁, y₁): [tex]y-y_1=m(x-x_1)[/tex]
(1, -5) ⇒ x₁ = 1 , y₁ = -5
Therefore:
[tex]y-(-5)=\frac16(x-1)\\\\\underline{y+5=\frac16(x-1)}[/tex]

4. Find the product of (a+b)(a²-ab+b?)
Answer:
a³+b³
Step-by-step explanation:
this is formula. You can also refer to the attachment
Answer:
Step-by-step explanation:
(a + b) (a² - ab + b) = a*(a² - ab + b) + b(a² - ab + b)
= a*a² - a*ab +a*b + b*a² - b*ab + b*b
= a³ - a²b + ab + a²b -ab² + b²
= a³ - a²b + a²b + ab - a²b + b²
= a³ + ab - a²b + b²

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.
A graph shows Number of Bushels on x-axis and Price of Corn in dollars on y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.
Previous Year
Number of Bushels
Price of Corn (dollars)
2
10
4
20
6
30
8
40
Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. (5 points)
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work. (5 points)
Answer:
Part A: 8
Part B: $1
Step-by-step explanation:
Part A: We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.
Divide both sides by 3 to get 1 bushel=$8.
We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.
The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.
Part B: In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1
Therefore, the price has increased by $1 this year.

2. Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost
track of how many of each ticket she sold; however, she remembered that she
was given 100 tickets and she collected $900. The system of equations shown
can be used to represent this situation: Part A: What does the variable x
represent in this system of equations?
A. The number of dinner tickets sold.
B. The number of dessert tickets sold.
C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets. ption 1
Answer:
A. The number of dinner tickets sold.
Step-by-step explanation:
Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold; however, she remembered that she was given 100 tickets and she collected $900.
Let us represent
Number of dinner tickets = x
Number of dessert tickets = y
From the above question, our system of equations is given as:
x + y = 100...... Equation 1
$10 × x + $6 × y = $900
10x + 6y = 900...... Equation 2
Therefore, the variable x in this system of equations represents the number of dinner tickets sold.
Option A is the correct option.

I dont understand the question
Explanation:
If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.

Write down the value of angle y, giving a reason for your answer
Y=
Other angle given is 67 degrees
Answer:
y would be 67 as well.
Step-by-step explanation:
they are alternate interior angles. hope it helps
In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
Part(a)
We have a triangle shown in the picture.
The two lengths of a triangle are equal.
The angle opposite to the sides will be equal.
As we know,
The triangle's interior angles add up to 180°.
180 = 55 + 55 + x
x = 180 - 110
x = 70 degrees
In part (b)
There are two parallel lines shown in the picture.
The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.
Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.
